Yes, that's where my fast IAT sensor is.

On a separate but related note...why not take the opportunity to relocate it out from under the UIM to avoid a little heat soak? With a little effort the connector can be reached and removed and just leave the old failed sensor in place. Use the plug n play harness and it’s completely reversible if ever desired and you don’t have the hassle (and some risk) of pulling the UIM off.

I wish I still had the laptop with the logs on it (it's been a while), but I can tell you I had a noticeable difference in AFR's on my Power FC when I switched sensors. With the dampening effect of the stock sensor gone, the hot starts and air temp compensation table needed to be retuned. That being said, the stock ECU may be more robust than a PFC that barely runs closed loop well. We just don't know. The air temperature compensation could be off, and Power could be down or, exhaust temperatures could be up, it's hard to say without any data. Any kind of time constant or delay timer or transient air temp compensation table in the ECU is going to be off with the new sensor.
I would say change the stock sensor without retuning at your own risk, whether it's stock ECU or some other ECU (Power FC).
